    • A preparation method of porous organic-inorganic mesopores is provided to disperse highly precious metals such as palladium by using chelate molecules, increase removal efficiency of harmful substances by preparing inorganic-organic mesopores using mesoporous organic-inorganic silica as a raw material, and easily adsorb a specific lipophilic harmful substance and highly disperse an active metal into cavities of porous mesopores by containing lipophilic groups in the structure of mesopores. A preparation method of porous organic-inorganic mesopores comprises the steps of: (a) mixing a mixed solution of a metal salt and a chelate compound, an organic-inorganic silica precursor, and a polymer surfactant mixture to form a meso-structure; and (b) removing a chelate agent and a surfactant from the meso-structure. The preparation method comprises the step of reducing porous organic-inorganic mesopores into which the metal salt is dispersed to prepare porous organic-inorganic mesopores into which metal is dispersed after performing the step(b). The metal salt is a salt of at least one precious metal of groups 8B to 11B. The metal salt is a palladium(Pd) salt, a platinum(Pt) salt, a gold(Au) salt, and mixtures thereof. The chelate agent is polyethylene glycol, polypropylene glycol, ethylene glycol, or mixtures thereof. The surfactant is selected from an ionic surfactant, an amphoteric polymer surfactant, and Pluronic.

    • PURPOSE: Catalyst and a method for preparing the same are provided to use plenty of electronic products without electricity by replacing energy. CONSTITUTION: A method for preparing catalyst includes the following: Zeolite, acidic component, and water are mixed to obtain a mixture. The mixture is dried at high temperature to obtain noble zeolite. The noble zeolite is used as catalyst. The noble zeolite is mixed with alkaline component and water. When energy is applied to the mixture with the noble zeolite, a continuous exothermic reaction and endothermic reaction are generated.
